Step-by-step explanation:
she gets $7.20 from selling the 18 chocolate bars
7.20 divided by 5.40 is 1.3333...
the 1 in 1.3333... represents the base 5.40 and the 0.3333... represents the profit
You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x
2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
